ALSA: mtpav: restore negation dropped in guard() conversion

Browse Source 
commit 316e0074ec ("ALSA: mtpav: Use guard() for spin locks")
claims to be "Merely code refactoring, and no behavior change", but
it accidentally dropped the "!" from

        if (! (portp->mode & MTPAV_MODE_OUTPUT_TRIGGERED))

in snd_mtpav_output_trigger().

Restore the negation.
